I experienced sudden hearing loss in my right ear with severe vertigo several years ago and was very sick. I was basically unable to care for myself, so yeah, very sick. Lots of trips to the hospital for tests, MRI's, CAT scans, numerous blood tests and all tests came back negative for anything. Finding a cause for sudden hearing loss is sometimes not possible as it was in my case and as sick as I was I thought for sure it had to be a tumor or something equally as scary, nope. Even my family doc thought it was bad news when he first saw me. Whatever it was took me down hard and did do some damage. I experience random bouts of tinnitus and vertigo. This all began in 2003 and I've been back a few times more for different tests with a neurologist and audiologist and still have not figured out the cause, all we know is that my right side is damaged. For this guy to just off handedly blame PG is ludicrous. I vape like a fiend and it has not once aggravated my situation.
Well there you go, now you know the cause. Let your doc know it's all good from here on. lol
